the numbers I found are...(D26)(GM72)and(3896339 with the letter N underneath the numbers) Thanks again by all means!!
I looked for that cast number and I'm not having any luck YET, It is a 12 bolt car correct? Did you find any other numbers on the axle tube?
Are you just wanting the Ratio or Wanting to know what the housing came out of originally?
